US Patent No. 334,620, granted January 19, 1886 to Edward W. Serrell Jr. for an improvement in silk-reeling machines. It uses two drums of slightly different diameter on one shaft, with a movable guide between them, so that silk thread stretched while drawn through the croisure can contract to its normal length before being wound onto the reel. The scan has two sheets of patent drawings (Figs. 1 and 2) and a two-page specification with a single claim. The specification also describes the lance-bout filament-attaching device and the electric-circuit levers that add cocoon filaments when the thread falls below the required size.
